Twitter introduces tailored tweets for brands, both Google Music and Rdio bring interface improvements to their Android apps, and web app integration comes to Ubuntu.

New targeting adds greater relevance to your Promoted TweetsTwitter introduced today a new feature that will have users receiving tailored tweets from brands based on their location. For instance, global companies that have different launch dates for different countries can send tailored tweets at different times for different countries. This will hopefully cut back on the amount of irrelevant tweets that users receive. [Twitter Advertising Blog]

Web App Integration in UbuntuIntegrated web apps are coming in Ubuntu 12.10, which means that web apps can be launched as individual windows separate from your main browser, from pretty much anywhere in the OS—including the HUD, Menus, Quicklists, and Launcher. Most of the popular web apps like GMail, Last.fm, and Google Docs are already supported, with more apps being added in the future from the development community. [jonobacon@home]
